This application principally concerns improvements in, or modifications of, a main invention described in 45714/99.

FIELD

This invention concerns fused azepinone cyclin dependent kinase inhibitors, compositions comprising these compounds, and methods for administering such compounds for diseases of cellular proliferation and/or abnormal protein phosphorylation.

BACKGROUND

A major advance in the understanding of the control of the cell cycle has been the discovery of a family of enzymes called cyclin dependent kinases (cdk).

Structurally they consist of a catalytic subunit and a regulatory subunit. The catalytic subunit is similar to the catalytic region in a number of serine/threonine S\ kinases and at least eight distinct subunits have been described (cdkl(=cdc2)-cdk8).

20 The regulatory subunit is necessary for activity and a number of proteins in this family have been described (cyclin A-cyclin Most cyclins can interact with more than one cdk and each known cyclin-cdk pair seems to have a distinct role in regulating the cell cycle. These activities are regulated not only through transcriptional and translational control of the subunits, but also through phosphorylation and dephosphorylation of the subunits. In addition, negative regulatory proteins have been discovered (p15, p 1 6

NK

4 p 2 1 cipl and p27Ki pl which bind to the cyclin-cdk complex and inhibit activity. Structural understanding of the cdks and their regulation has been advanced by the solution of crystal structures for cdk2, cyclin A, cdk2-cyclin A, and cdk2-cyclin A-p 2 7 k ip l [Russo et al., "Crystal Structure of the p 2 7 Kip l Cyclin-Dependent Kinase-4 Bound to the Cyclin-A-Cdk2 Complex," Nature, 382(6589):325-331 (1996).] \\mlbflc\hoe1icusann\Jccp\Spcci 4 5 14-99. Divisional SPECI.doc 16101/01 -2- It is clear then that the cdks are important in the control of the cell cycle. As a result, it appears that alterations in cdk expression, function or regulation are associated with diseases of cellular proliferation. Alterations that would increase cdk activity (overexpression of the catalytic and/or positive regulatory subunit, or underexpression or deletion of negative regulatory proteins) have been reported in many cancers. The most common observation has been the deletion of the p 16 (also called MTS 1, CDKN2, p16INK) gene. This gene codes for a protein that inhibits the activity of cdk4 and cdk6. This loss of inhibitory activity has been observed in a wide variety of primary human tumors and human tumor-derived cell lines, including lung, breast, brain, bone, skin, bladder, kidney, ovary, liver, colon, pancreas and leukemias. Overexpression ofcdkl in ovarian carcinoma and overexpression of cyclin D in non-small cell lung cancer also has been observed.

Clinical studies have shown that alterations in cdk pathways have prognostic significance. Deletion of the p16 gene has shown to be associated with poor prognosis in B cell lymphomas Garcia-Sanz et al., "Deletions and Rearrangement of Cyclin-Dependent Kinase 4 Inhibitor Gene p16 are Associated with Poor Prognosis in B cell Non-Hodgkin's Lymphomas," Leukemia, 11(11): 1915- (1997)], and pediatric acute lymphoblastic leukemia U.R.

An important signal for proliferation of vascular smooth muscle cells is increased expression of cdk2 and associated regulatory subunits, cyclin E and cyclin A. C.

Biochem., 167(1- 2):99-105 (1997)]. inhibitors of cdk5 should be useful in the treatment of the disease.

\\mlb-rilks$om cs\luzc\ \Scc\Sp57o a 4-99.1 DivisioalSPECd &c 16/01/0) The potential role of cdk inhibitors in therapy of numerous diseases has led to efforts to find small molecules that inhibit all or some of the cdks. Several small molecules have been discovered that inhibit cdks specifically. These include the purine analogs, olomoucine, roscovitine, and CVT-313; the flavonoid, flavopiridol; and butyrolactone I. Other potent inhibitors of cdks are known, including staurosporine, UCN-01, and suramin, but these compounds also are potent inhibitors of other protein kinases. Crystal structures for several specific cdk inhibitors in complex with cdk2 have been determined, including olomoucine, roscovitine, and flavopiridol. One specific inhibitor of cdks has reached clinical trials, flavopiridol Sadlacek et al., "Flavopiridol (186-8275, NSC-649890), a New Kinase Inhibitor for Tumor Therapy," International Journal of Oncology, 9:1143 (1996)], which has shown antitumor activity in Phase I trials in a number of tumor types and is progressing to Phase II trials. All other known cdk inhibitors have been shown to inhibit the growth of tumor cells in culture, although none are as potent as flavopiridol. No in vivo anti-tumor studies have been reported for these compounds, although there is an anecdotal report of a response to olomoucine in a spontaneous dog melanoma.

Several cdk inhibitors have shown activity in models for other diseases.

Animal studies have shown that CVT-313 is an effective inhibitor of neointimal proliferation in a rai resienosis iulecl. D1'rs U t al., .Cv T-J, a Su u a Potent Inhibitor of CDK2 that Prevents Neointimal Proliferation," J. Biol. Chem., 272(46):29207-11 (1997).] Roscovitine has been reported to improve renal function in a rat model of glomerulonephritis, and to be an inhibitor of human cytomegalovirus replication in culture. Roscovitine also inhibits DNA synthesis in 25 plasmodium falciparum, the malarial parasite. R. Graser et al., supra.

7,12-dihydro-indolo[3,2-d][ ]benzazepin-6(5H)-one is a known compound.

This compound originally was synthesized by Dr. Conrad Kunick, then at the "Pharmazeutisches Institut der Universittt Bonn. C. Kunick, "Synthese von 7,12dihydro-indolo[3,2-d][1]benzazepin-6(5H)-onen und 6,11-dihydroindolo[3',2':2,3]azepino[4,5-b]indol-5(4H)-on," Arch. Pharm. (Weinheim), 325:297- 299(1992).

\\lbfilcs\homsuannl\Kep\SpcMS 7 l 4 -99 I DiomaI SPEC[ doc 16/01/01 From the above discussion it is clear that known cyclin-dependent kinase inhibitors are useful for treating diseases of cellular proliferation and/or abnormal protein phosphorylation. But, there still is a need for new potent, and preferably selective, cdk inhibitors.

H 0 H 0 H COEt R DMSOIO R R HO O Scheme 4 On the basis of the ring system of Formula 2, the synthesis of compounds according to the present invention may be achieved by the following strategies: rs Introducing substituents in Ring A, and formation of heterocyclic rings. Substituents can be coupled to position 2 via electrophilic aromatic 5 substitution at several stages in the synthetic pathway. For example, halogens and nitro substituents can be introduced. Other substituents can be introduced by nucleophilic exchange of the halogen or via diazonium intermediates, derived from the nitro compound. Carbon chains may be introduced at the 2 position by palladium catalyzed reactions employing halogen substituted derivatives. For compounds having one or more substituents in positions 1, 3, and/or 4, or a hetero atom in ring A, the synthetic route starts with an appropriate amino-substituted aromatic carboxylic acid. An example of this strategy is provided below as Scheme \\mclb-flc\home$\s.anet\Kep\SpecM45714-99 I Divisional SPECI doc 16101/01 20 OMe OMe EtOH, HC1 H I 2 Et OMe OMe H H 0 N Nt HO C2 *OMe H OMe H 0 NH 0 N H:N N I Br 0 N

A nitrogen substitution at position is achieved by reaction with an alkyl halide in the presence of a base. Sulfur can be exchanged for the oxygen by reaction with phosphorus sulfide. This thiolactam serves as starting material for compounds annelated at the 5,6 site, or the synthesis of methylthioimidates by reaction with iodomethane.

Introducing substituents into the D-Ring. Substituents intended at position 9 or 11, or appropriate precursor groups, are included in the phenylhydrazine (Scheme Substitutions at position 10 are included via electrophilic aromatic substitution. Halogen substituents, e.g. the bromo substituent in the 9, 10 or 11 position, may be exchanged for other substituents, e.g. the cyano group, via a Rosenmund-von Braun reaction. The bromo substituent furthermore may serve as a reaction center for palladium catalyzed coupling reactions, e.g.

Heck-reactions. Methyl substituents at positions 9 and 11 may be oxidized to carboxyl groups, which can be transformed by well known methods to other functional groups, e.g. alcohols, esters, ketones, aldehydes, etc.

Introduction of substituents in position 12. The nitrogen in position 12 can be alkylated selectively with alkyl halides using appropriate bases. Aminoalkyl chains can be placed at position 12 by a Mannich reaction.

Substitution of the indole part C,D for other ring systems. The aryi-(CO)-CH 2 motif of the intermediate shown in the Schemes above provides the structural basis for the annelation of various heterocyclic ring systems. For example, the following heterocycles have been annelated at this site utilizing the electrophilicity of the keto function and the C,H-acidity of the CH 2 group in the vicinal position: pyrazoles, pyrimidines, pyranes, pyridines, quinolines, and quinoxalines. Alternatively, the lactam ring closure strategy can be used for the preparation of the derivatives in which the C,D-system is substituted for another system.

In Vitro Human Tumor Cell Line Assay W0 The. huiman tumor cell line creepningy procrer uses n diverzP diepneporiented panel consisting of approximately 60 different human tumor cell lines organized into disease-specific subpanels. The compounds of the present invention were tested over a range of concentrations for cytotoxic or growth-inhibitory effects against cell lines comprising the panel. The eight subpanels represented diverse histologies (leukemias, melanomas, and tumors of the lung, colon, kidney, breast, *ovary, and brain).

Compounds of the present invention were tested over a period of several days. During this period the cells were continuously exposed to various concentrations of the compounds tested.

Three different response parameters were evaluated. The first response parameter was the growth inhibition ("GIs 0 GIso is the concentration of compounds made according to the present invention that results in an apparent 50% decrease in the number of tumor cells relative to control tumor cells (not exposed to the compounds of the present invention) at the end of the incubation period.

The second response parameter was the total growth inhibition TGI is the concentration at which the number of tumor cells remaining at the end of the incubation period substantially equal the number of tumor cells existing at the start of the incubation period.

The third response parameter was the lethal concentration ("LC 5 LCso is the concentration of compounds made according to the present invention that caused an apparent 50% reduction in the number of tumor cells relative to the number of tumor cells present at the start of the incubation period.

In a typical GIso mean graph left graph of FIG. the relative position of the vertical reference line along the horizontal concentration axis was obtained by averaging the negative logioGIso values for all the cell lines tested against the compound. Horizontal bars were then plotted for the individual negative logloGIso o, ine ,elt;iv to the ,ertial reference in. The Gl rraph ths provides a characteristic fingerprint for the compound, displaying the individual cell lines that are proportionately more sensitive than average (bars extending to the right of the reference line) or proportionately less sensitive than average (bars extending to the left of the reference line). The length of a bar is proportional to the difference between the logioGI 50 value obtained with the particular cell line and the mean (represented by the vertical reference line).

In vitro time course assays were performed with this compound in order to determine the concentration and duration of drug application necessary to inhibit cell proliferation. Four cell lines (CoLo-205, HL-60 TB, A-498, UO-31) were cultured in media containing the compound for incremental times, then were switched to compound-free media for the rest of the observation time. The results (illustrated in FIG. 31 and 32) indicate that this particular compound causes total inhibition of growth (as measured by GIn.o TGI and at 2-5 uM and that short exposures were sufficient for maximum inhibition. Cells exposed to the compound for 48 \\mlbfilc\homeSwSUZ\s e\JCctV\SpeCiMS714.99 I Diviioml SPEd 16/01/01 -51 hours required a lower concentration of 1-3 tM to achieve total growth inhibition.

These data are effective in determining a dosing schedule that achieves maximum cell growth inhibition, a plasma or blood level concentration of 2-5 pM compound when exposed for 45 minutes once per day.

Initial experiments to determine if these exposures are achievable in animals were done in Sprague Dawley rats. A single i.v. dose of this compound dissolved in DMSO was given to two animals, one at 5 mg/kg and one at 10 mg/kg. Plasma concentrations of the parent compound were determined by HPLC assay and are listed in the table. At 5 mg/kg the half life in the plasma was 46 minutes, clearance was 16 mL/min/kg, and concentrations in excess of 2 AM were maintained for over two hours. At 10 mg/kg the half life in plasma was 66 minutes, the clearance was 14 mL/min/kg and concentrations in excess of 2iM were maintained for over three hours.

Example 31 This example describes the method used for hollow fiber in vivo testing of mice. Human cancer cells were cultivated in polyvinylidene fluoride (PVDF) hollow fibers. A sample of each cancer cell line was implanted intraperitoneally and subcutaneously in mice. Each mouse received plural fibers, several both ;intraperitnely and subcutaneonuly, rpnresenting distinct cancer cell lines. Mice were treated with 9-bromo-7,12-dihydro-indolo[3,2-d][1]benzazepin-6(5H)-one N\nfcib-fikcs\hofnsuzan ccp\Sped 5714-99. I Divsionl SPECI doc 16/01/01 -64made according to the present invention at each of two test doses intraperitoneally using a QD X 4 treatment schedule. Vehicle controls consisted of mice receiving the compound diluent only. The fiber cultures were collected on the day following the last treatment. Anticancer effects were assessed by determining viable cell mass for each of the cell line using a formazan dye (MTT) conversion assay. From this, the %T/C was calculated using the average optical density of the compound-treated samples divided by the average optical density of the vehicle controls. In addition, the net increase in cell mass was determined for each sample as samples of fiber cultures were assessed for viable cell mass on the day of implantation into mice.

This allowed cytostatic and cytocidal capacities of these compounds to be assessed.

Example 32 This example describes a method for treating humans with the compounds of the present invention. Compounds satisfying Formulas 1 and/or 2 are obtained.

15 These compounds are then administered orally or intravenously to humans at a dose of from about 30 mg/kg of subject/dose up to about 400 mg/Kg of subject/dose, but preferably between about 30 mg/Kg of subject/dose to about 50 mg/kg of subject/dose, or to provide a total amount of compound or compounds to the subject per treatment of from about 0.1 gram to about 3 grams.
